Yellow River in Kaifeng air separation group co., Ltd., formerly known as complete set of auxiliaries in Kaifeng air separation group company, founded in the late 1970 of the 20th century, reformed as a new type of joint-stock enterprise groups in late 2003. after years of struggle and hard work, the Yellow River in the air separation process of opening up markets at home and abroad has added new vitality, and embarked on a path of sustainable development. Yellow River empty min in "quality Hing enterprises, and integrity career" of business concept Xia, adhere to technology innovation, and management innovation, and system innovation, in more short of period within implementation has across type development, now set empty min device performance has up more than 300 over sets, is production manufacturing of empty min device is 35000m ³ /h; has input run 3 years of empty min device for 28000m ³ /h within compression process empty min ; Cooperation with Linde company produced two sets of 60000 m ³ /h; large air separation technologies reserves up to 53000 m ³ /h levels, air separation products all over the domestic metallurgy, oil and petrochemical areas such as coal, chemical fertilizer, chemical, building materials, and exported to Nigeria and Uzbekistan and other countries. as of now, China Jiangyin huaxi gas co., Ltd. as the representative of "returning visitors" users has reached nearly 50.undefined Institute of design in the company, to domestic senior space experts to technical team leader, played an active role in the research and development of high-tech products. the company continued to increase its investment in technology, adopt international advanced molecular sieve adsorption purification, turbo-expander, structured packing Tower, full distillation argon recovery and DCS control technology, using international advanced calculation of heat transfer calculations, rectifying, stress analysis, three dimensional calculation of tubing, fluid dynamics, and other software for product design. so far, company has has "double metal connector", and "double main cold empty min device", and "compressor within fin tablets tube heat exchanger", and "new fittings rolling slot machine", and "through flat expansion machine seal structure", and "can adjustable eccentric can pour Vava block", and "large wing t type fixed ring", and "efficient energy saving Tower", more items national invention franchise and practical new franchise. the company's industry-leading levels of new air separation technology in product design and development, new technologies, effectively ensuring the advancement, stability and reliability of air separation plant, forming a unique characteristic of air separation of the Yellow River full distillation argon recovery technology and manufacturing process of fractionating Tower. complete set of air separation of the Yellow River of air separation unit classics--15000m ³ /h full distillation argon series ASU won the high-tech product certificate of Henan province.

expert group dedicated to precision manufacturing technology of air separation of the Yellow River to build core equipment-distillation Tower of air separation units, in addition to the tower structure is designed to be fully improved, it has also increased input from process equipment in the manufacturing, assembly using more scientific reasonable processing methods, the company of sieve plate column, better quality of structured packing Tower. in guarantee fractionator quality Shang, site technology expert group in production practice in the, gradually development and master has many proven of technology technology, Yellow River empty min unique of distillation column assembled technology job method simple, can control ability strong, greatly improve has products quality, are has practice of test; Yellow River empty min independent development of fractionator tube body manufacturing technology, makes Tower body weld reduced 30% around, not only elimination has quality defects, also makes Tower body overall strength and stability has has significantly improve ; Unique sieve-plate column of air separation of the Yellow River between fixtures, effective control of plate deformation, distillation condition more stable.

centrifugal air compressor is the development and manufacturing of air separation of the Yellow River main supporting units of large and medium-sized air separation plants, according to the practical needs of the company, continued to adopt new technologies, new processes to improve and perfect, in the design, manufacturing, assembling, installation and operation, has accumulated a wealth of experience. the development and manufacturing of centrifugal air compressors air separation of the Yellow River main h-and DA-two categories. H-gradual cooling compressors to two-axis, four-level compression; DA-type four-stage compression compressor for single-axis stage cooling. compressor used advanced computer software design of ternary flow impeller, and efficient leaves spread pressure device, and efficient imports guide leaves, and high precision carburizing hard tooth surface of high speed overload growth gear, and new can pour Watts bearing, and efficient large sets tablets type Middle cooling device, and new can regulation and automatically compensation hot deformation of middle tracheal road, advanced of technology and structure, entire unit has structure compact, and layout reasonable, and isothermal efficiency high, and workers condition range wide, and vibration small, and noise low, and operation maintenance easy, advantages. after a long period of practice has proved that the air compressor in air separation of the Yellow River developed and manufactured quality, reliable, stable operation, performance and indicators rank level of industry-leading technology.

target design, create personalized air separation. air separation process of air separation equipment in research and development of the Yellow River, attaches great importance to energy-saving emission reduction of air separation units, is designed to reduce equipment energy consumption indicators, create greater economic and social benefits for the user. Yellow River empty min development of new empty min process of the performance index reached domestic advanced level, to its low energy consumption, and adaptability wide of advantage, in rich oxygen spray coal iron, and nonferrous metals smelting, and part coal chemical area has broad of market; development of empty min energy saving new technology makes device integrated energy consumption reduced 5%; development of seven species system nitrogen process can meet different user on nitrogen products yield, and varieties, and purity, and pressure of needs, System nitrogen device performance index industry leading ; Development of energy-efficient distillation column for stable operation and energy-saving and consumption reduction of air separation equipment has laid a solid foundation. by the market research, the Yellow River of air separation unit average energy consumption below the industry sets of air separation device index 3%-5%.

argon technology in the industry to see air separation system of the Yellow River, due to positive full distillation argon recovery technology to develop new products, 1500~35000m ³ /h of different specifications with Argon-argon system of air separation plant has formed ten product series, and successfully put into operation all, argon product yield and purity are met or exceeded the design specifications.undefined 12000m ³ /h air separation equipment of the technical indicators are among the leading domestic level, especially the argon extraction rate of 84%, become a series of Yellow River with Argon in air separation plant successfully developed model of commissioning.
